I bet their going to offer Integral Active steering as an option since in corners it will make it turn in like a shorter wheel base car. Plus if you see the wheel base on the current 2.0 inches longer than the current E9X platform. On a side note if you look at BMW's from the past such as the E30 (3-series) E34 (5-series) and E32 (7-series) the back wheel well also was lower compared to the front. Maybe they are going back to more retro styling on the new F30 3-series.
